How do I bypass a goggle account sign in from previous owner on my galaxy s7

I have factory set my galaxy s7 and am now setting it up however when it gets to the goggle sign in it asks me this. " This device was rest.To continue , sign in with a goggle account that was previously synced on this device. Well how am I to know this when I've no clue whom that it used to belong too...?????? "

Welcome to the forums. This security measure can't be bypassed. You need to get the previous owner's credentials, without them you have an useless device on your hands. I hope you understand the reasons. Sorry.
